F70-74: Bartelme takes the age group in Chicago's summer heat

• Delma Bartelme won the F70-74 age group in 2:36:16 (11:55/mi), finishing more than 23 minutes clear of her only competitor.
• Claire Carder completed the half marathon in 2:59:34 (13:42/mi), breaking the three-hour barrier — just.
• Bartelme was the stronger closer: her 15K-to-finish split ranked 2,036th among all women, versus Carder's 2,482nd, a gap that reflected the margin built throughout the race.

With just two finishers in the F70-74 age group, this was a small but genuinely impressive field — two 70-year-olds covering 13.1 miles on a warm Chicago morning (72°F, with a 10 mph wind doing little to cool things down). Completing a half marathon at this age, at any pace, is worth noting before anything else.

Bartelme, racing on home turf in Chicago, was in control from the start and kept building. Her women's field placing improved steadily at every checkpoint — from 2,432nd early on all the way to 2,148th by the finish — a consistent, progressive effort that never wavered. Her 11:55/mi average held up through the final stretch, and her closing split was the sharper of the two.

Carder, traveling from Portland, worked hard across the full distance. Her women's field placing also climbed through every checkpoint, from 3,012th down to 2,822nd by the finish, showing she was moving through the field even late in the race. But Bartelme had simply established too large a gap to threaten, and Carder crossed in 2:59:34 — a finish that will sting for its proximity to the three-hour mark, but a genuine achievement on a warm day nonetheless.
